Abstract: Various embodiments of a system and associated method for detection of subject activity by processing video and other signals using artificial intelligence are disclosed herein. In particular, a subject monitoring system is disclosed that monitors subjects using a video-capable camera or other suitable video capture device to identify a subject's status of an individual by monitoring subject actions in real-time. The system further monitors other persons in the room with a subject to identify their actions and identities to ensure safety of the subject and facility while preventing confusion of the system as multiple individuals step in and out of frame over the course of the collected video feed.

Abstract: A system eliminates artifacts from an electrocardiogram signal. The system includes a monitor for receiving an electrocardiogram signal from a patient and a microprocessor utilizing a shift-invariant wavelet transform for decomposing the electrocardiogram signal into a plurality of scales. The microprocessor applies rules to the scales for removing artifacts from the scales. The microprocessor reassembles the plurality of scales to produce a reconstructed and accurate electrocardiogram signal without the artifacts.
